Instructions

- Bright flashlight

- Clean lint-free cloth
- Turn the canister off, unplug it by holding the plug, allow it to cool, and fully disconnect the hose and floor tool before inspection.

Confirm the DC21 configuration
DC21 (DC21) is a bagless canister body with a retractable cord, flexible hose, wand, and electric Motorhead connected through the powered hose and wand. U.S. DC21 Stowaway canister with a motorized brush bar, powered hose/wand path, internal head drive, and retractable cord reel.. Cataloged variants include DC21 Motorhead, DC21 Stowaway Motorhead. Match the machine code and serial label before ordering a filter where fitted, variant-correct floor tool, bin, hose, wand, or external seal; a retail family name can cover incompatible hardware.
Empty before the maximum-fill mark
Remove and empty the clear canister bin and cyclone inlet using the documented release. Keep the opening downward and avoid forcing the ejector, lid, or latch.
Clear the inlet and closing surfaces
Use a soft dry brush or cloth to remove compacted dust from the inlet, outlet screen, shroud area that the guide exposes, lid edge, latch, and sealing surfaces. Do not insert tools into the cyclone or motor inlet.
Inspect the complete container
Look for cracks, a warped lid, a missing or rolled seal, a loose hinge, or a latch that will not hold. Replace the complete owner-removable container or documented seal rather than gluing a structural or sealing surface.
Refit and confirm a flush seal
Install the empty, dry container in the documented orientation. Confirm the lid and container click fully into place, then make one short test. Stop if dust escapes, the bin loosens, or airflow remains weak.
